WASHINGTON—Federal regulators are likely to take action before summer's end against Fiat Chrysler Automobiles NV over lapses in handling older Jeeps tied to fiery rear-end crashes and millions of other recalled vehicles, the head of the National Highway Traffic Safety Administration said.

Mark Rosekind, the agency's chief, on Thursday said he expected to penalize Fiat Chrysler by as soon as the end of July and "absolutely" before Sept. 7. He said the agency could levy fines and force vehicle buybacks if regulators determine the company violated federal law governing how auto makers must conduct recalls. The agency and the company could also settle, he said, with Fiat Chrysler signing a consent order admitting to certain lapses and agreeing to penalties.

Mr. Rosekind's comments, following an unprecedented regulatory hearing at U.S. Transportation Department headquarters, ratcheted up simmering tensions over allegations that Fiat Chrysler has misled and obstructed auto-safety regulators.

During Thursday's hearing, regulators said the auto maker hasn't performed adequate repairs or properly alerted car owners or the government to safety problems with more than 11 million vehicles spanning 23 recalls. Asked if he could foresee avoiding an enforcement action against Fiat Chrysler, Mr. Rosekind responded: "No."

Regulators have "raised some legitimate questions about the way [Fiat Chrysler] has managed certain safety recalls," said Scott Kunselman, the company's senior vice president for vehicle safety and regulatory compliance, addressing NHTSA officials during the hearing. The auto maker "could have done better in carrying out the campaigns you identified. We have learned from our mistakes and missteps," he said.

He said Fiat Chrysler created a new employee position to monitor recalls and alert him and regulators to problems. In addition, the company is working with suppliers to quicken design and production of repair parts.

A Fiat Chrysler spokesman declined to comment on Mr. Rosekind's remarks.

The sustained scrutiny over Fiat Chrysler's handling of vehicle safety comes at a delicate time for the auto maker, as Chief Executive Sergio Marchionne seeks a merger partner in part to help defray looming costs for technology and emissions compliance. Depending on the outcome of regulators' probe, Fiat Chrysler could be forced to pay hundreds of millions of dollars in fines. Later this month, Fiat Chrysler will appear before a judge to argue for a new trial in a Georgia case where a jury awarded $150 million of legal damages over the death of a 4-year-old boy in a Jeep fire.

With older Jeeps featuring rear gas tanks under scrutiny for their potential to catch fire in rear-end crashes, Fiat Chrysler resisted requests from regulators to test a suggested fix and lagged behind in producing parts for repairs and getting vehicles serviced, an official in NHTSA's defects investigations office said.

Witnesses at Thursday's hearing read prepared statements without taking questions. In addition to auto regulators, safety advocates and consumers decried Fiat Chrysler's handling of more than 1.5 million recalled Jeeps and other defective vehicles.

Clarence Ditlow, executive director at the Center for Auto Safety, said Fiat Chrysler uses vehicle-owner notification letters to "get out of jail" and then delays carrying out repairs. The father of a 17-year-old boy killed in a fiery rear-end Jeep crash in November 2013 said he didn't receive a recall notice about the vehicle until long after the accident.

Fiat Chrysler sought to have Thursday's hearing canceled, arguing it had taken steps to improve its approach to safety defects and fares better than the industry average in completing recalls.

Fiat Chrysler is installing trailer hitches on the backs of recalled Jeeps to provide better protection in lower-speed collisions. Federal regulators have noted that only 21% of recalled Jeeps had been repaired as of April 30.

Mr. Ditlow expressed concerns about dealers declining to install trailer hitches on rusty Jeeps. A Fiat Chrysler spokesman Thursday said the company will repair vehicles "that will accommodate service."

The company says it has now addressed more than a half million of the Jeeps, some of which previously featured trailer hitches and didn't need repairs.

Still, the rate of repairs "are not in line with Fiat Chrysler's own projections or NHTSA's expectations," said Scott Yon, chief of the vehicle integrity division in NHTSA's Office of Defects Investigation, during the hearing. He said the auto maker's recall performance differs from peers.

"Fiat Chrysler takes a long time to produce the parts needed to get vehicles fixed," he said. He added that dealers have problems getting parts, customers face difficulties getting repairs and proposed fixes often don't remedy vehicle defects.

Other NHTSA officials pointed to the auto maker providing misleading or inaccurate information to the agency and failing to notify vehicle owners about recalls within 60 days of telling regulators about safety defects.

Regulators before Thursday's hearing already "tentatively concluded" the auto maker suffered lapses handling recalls. Other recalls being scrutinized include those involving Fiat Chrysler vehicles equipped with rupture-prone air bags manufactured by Takata Corp. of Japan. Another recall involves ignition switches that can slip out of the run position, cutting engine power and disabling air bags.

In addition, regulators have opened investigations into recalled Fiat Chrysler vehicles that continue to catch fire after inadequate repairs to headliner wiring; inadvertent air-bag deployments that continue after attempted fixes; and delays in addressing vehicles with defective left tie rod assemblies.

Fiat Chrysler in June 2013 agreed to recall roughly 1.56 million Jeep Grand Cherokee and Liberty sport-utility vehicles with model years ranging from 1993 to 2007 and gas tanks installed behind the rear axle.

More than a million others are subject to a "customer satisfaction campaign" in lieu of a recall. Regulators, after previously requesting those Jeeps be recalled, later determined they posed no unreasonable safety risk.

Fiat Chrysler's Mr. Marchionne met privately with senior regulators in June 2013, leading to a deal for the limited recall with no admission the vehicles were defective.

Fiat Chrysler says the Jeeps are safe and that other vehicles, some with similar fuel-tank designs, are more often involved in fiery crashes. The company contends the recalled Jeeps only catch fire in severe, high-energy crashes and that the vehicles met government safety standards in place when they were sold.
